There is a great deal of water on this earth of ours and a great deal of land underneath it.

All the treasures of these hidden plains are simply put away for our future use by bountiful nature, as prudent parents put money in the savings bank for their young ones. —-

Already in Chili they are mining coal under the bed of the Pacific Ocean, and the traveler may ride on electric cars through solid tunnels of coal beneath the waters of the greatest ocean.

The tin mines in Wales extend far out beneath the sea.

Workers in the Calumet and Hecla mines work beneath the waters of Lake Superior.

Oil wells are worked out beyond the edge of the Pacific Ocean. You may see the oil derricks just off Santa Barbara’s surf.

In the bay of San Francisco artesian wells, going through the preliminary depths of salt water, bring the water of fresh submarine springs to the surface.

But these little enterprises are but faint beginnings of the great work that man has to do in exploiting the wealth beneath the waters covering two-thirds of the earth’s surface.

This earth will be quite a romantic abode when sub-oceanic exploitation reaches full development, when the great gold mines beneath the waters are indicated simply by latitude and longitude.

Mars, with his huge canals distributing a planet’s waters scientifically, will be matched perhaps by our network of tunnels under the water from here to Asia, and by our boring, with the aid of cooling mediums, toward the earth’s centre and bringing up metals in a molten state.

Before he finishes with her, man will make old earth know that he is at work “in her midst.” He will make the harnessing of a tiny Niagara or the boring of a poor little isthmus seem feeble efforts.
